Application filed September 8, 11914.

To all tlf/'ioni 'it may concern:

Be it lniown that l, WILLIAM WESLEY Cool-m2, citizen of the `United States, residet il rtytoit in the county of Luzerne end State of ftennsylviinia., have invented certain new and useful improvements in CoaLW'ashing ililnchines; and l do declare the following to be a full, clear, and exact description of the invention, such as will enabl ers skilled in the art to Which it api c nis to ineke und use the saine.

i invention relates to improvements in chilies tor Washing cord and separating suine from rock and slate by specilic gravity.

Heretot'ore, it has been counnon cnnstroction te provide a vvveeihing receptacle having a cool discharge opening at a coinperatiyely nigh point and a rock and slate discharge opening et a relatively W point. The letter opening is usually normally closed by a manually operable gate. This construction has numerous disadvantageons features to overcome which l have primarily designed the construction to hereinafter described.

@ne of the main dillicnlties with machines of the "ype shove mentioned, is the 'fact that siste rock is prone to rise within the washing receptacle to such an extent is to allow a portion thereot to he discharged with the washed coal and, on the other hand, should ont n small quantity ot slate or rock accumulate, certain amounts of coal will invnriebly he discharged through the slate and rock outlet. In order -x' overcome these undesirable features. T. hive provided the construction herein described and claimed as shown in the drawings wherein:

Figure .l is o vertical longitudinal secmgh a coal washing machine illus. n applic-.dion ot' my invention 2 is n vertical section as seen il ot Fig. l; 3 is a horizontal section teken on the line 3-3 of Fie. il vand Fie: -l is e vertical transverse section the line vwl-l oi Fig. l. aocomrimny'ing drawings. l haw shown a coal washing machine comprising :in upright tenir having n transverse pnrtition 2 in njiper portion. the lower ond ot' the tank l being' suitably shaped to guide the nniterizrl therein into a vnlved discharge nine 25. To side of the partition a i :is provided which is here shown by upright connecting rods o Specification of Letters Yatent.

cated directly opposite the side wall against which the plunger l reciprocates. As is coinnion with devices o1'1 this character, the grato 8 inclines downwardly from its inner to its outer end thereby facilitating' the discharge of rock or slate through a transverse openincT l1 formed in the wall l0 above said grate, a suit-ably constructed carrier l2 heing' provided for the purpose of conveying the rock and slate,v discharged through the opening l1, to n remote point.

By reference more particularly to Fig. l, it will he seen that the Wall 'l0 terminates alle suitable distance above the opening 1l and that conifeying trough 13 is continued tronrthe casing` at this point, an endless carrier ll being provided in the trough 13 for the purpose of con\f'eying woshedcoal from the tank :2 in :t manner to be described.

. llt will likewise be noted that a second grate 15 is provided whose outer edge is located in Contact with the upper end of the wall l0, said grate inclining downwardly and inwai-diy from its point of Contact with said wall and tciii'iiimtiiig' a suitable distance above the grate 8.

Suspended upon a pair ot hinges .lo one leaf oli' each of which is secured to the wall ll). is a tr-.insrcrsvly elongated rectangular doo:- li which is loi-ated in aud subsl'intinlly closes tir. opcningrv il lander normal conditions. said door being provided with an inwardly and upwardly extending opl-raming; nrin lo lo whose upper end an upright operating link l! is pivoted, said link rising through an opening 2() in the ,enit-c lh and boing pivoted at. Ll to a first lever 22 which is lnlcruuied in a fork which rises troni the top olf thc tenir. l, a weight 2l boing provided on the free end of 'the lever li/ whereby to normally close the door l? through the instrumentality of the rod or link .19, it being understood that said door is designed to swing' outwardly.

ll'ith the parts above described the operation of the device is as follows: The newly mined coall with a considerable means before, described,

'W'her rile weight oi the ecoumulate. rock and siete is suioieuto overcome the Weight A, the door 17 will be forced outwsrfily thereby discharging en amount of msiseriel into e trough 122 in wliielfi rire' endless eonv'eyer 12 operates, l will therefore, be seen .ther the :groir'isioii si' lle euiometioelly opene floor :ergste l? prevents elle rook eno. siete from accumulating to en extent suiroient no allow elle same io be discharged through the coal outleif.

The upward; pressure of weiser reciy above the grate l5 is considerably Y iess than the pressure above izlie uncovered portion of lie grate 8, this being caused by the feet that the water musil be force-rl through "awo grstes at this point.
